In the games, Mt. Silver is off-limits to all but the most skilled of Trainers. After the player has received all sixteen badges of Johto and Kanto, Professor Oak will give the player permission to travel here.
The route to the area is rough, though no HMs are explicitly required to reach the Pokémon Center just outside the entrance. Inside, however, the cave is dark, requiring Flash to see. Many high-level Pokémon reside in the cave, including rare Pokémon not found elsewhere in the Johto region, like Larvitar and Misdreavus.
The cave has only one entrance, unlike all other caves found in Pokémon Gold, Silver, and Crystal, but goes deep into the mountain. In the cave's final room, the player will encounter Red, who will wordlessly challenge the player to what is the highest-leveled Trainer battle in the Pokémon series.
In HeartGold and SoulSilver Versions, Mt. Silver is much larger than before. Flash is no longer needed to light up the cave. The higher sections of the cave, where Red is located, require Rock Climb to be accessible. In addition, a hailstorm is present at the summit; this weather can become diamond dust on certain days. At times, the player must also venture onto the slopes on the mountain's sides in order to climb higher.

In the anime, Mt. Silver is the home of Silver Town, a city that boasts at least 30 inhabitants. Silver Town's main attraction is the Silver Conference, the Johto League's yearly tournament that brings tourism to the city.
In the Pokémon Adventures manga
In the Gold, Silver & Crystal arc of Pokémon Adventures, Red goes to the springs in Mt. Silver to recuperate from injuries he suffered from being frozen by Lorelei's Pokémon during the Yellow arc. While there, he meets Sabrina, a former enemy of his, who is there to recuperate from similar injuries.
Later, Red and Gold leave to Mt. Silver to train together.
Trivia
Though Mt. Silver appears relatively deep into Kanto, it is identified as a Johto location by the Pokégear.
Mt. Silver was called Shirogane Mt. in the Gold and Silver deluxe edition of the Pokémon Master Trainer board game. Because its release predated that of the games, it used the Japanese name.
Red's Pikachu, who can be fought here at level 88 (level 81 in Generation II), is the highest-leveled Pokémon of any in-game Trainer in the series.
In the original player's guide to Gold and Silver, there is mention of a "?" Pokémon that appears near the waterfalls in Mt. Silver at midnight or very early in the morning; however, this was a false rumor. The guide also claimed that the unknown Pokémon was supposed to represent legendary Pokémon found in Generation I that did not appear in Gold and Silver (which were programmed in and tradable from Generation I anyway).
Like Snowpoint City, Mt. Silver's summit features diamond dust on certain special days in Generation IV, including the anniversary of Gold and Silver's original release.
Mt. Silver is marked as a Johto location by the Pokégear; however, all squares immediately surrounding it (including those to the west of it) are marked as Kanto areas by the Pokégear in Generation IV. This issue was not present in the Generation II map, which placed it directly above New Bark Town.
The exterior of Mt. Silver is the only Johto area with Kanto characteristics, like the rocks, tall grass, trees, and the Pokémon Center itself. However, in Generation IV, the only major differences are the rocks and trees; for example, the trees placed in the high exteriors of the mountain itself are the ones commonly found in Johto.
In Generation IV, whenever the player is in or on the mountain, the location bar will always say "Mt. Silver Cave", even when the player is not inside the cave.
Origin
Mt. Silver is based on Mt. Fuji in the real-world Japan.
